Trigonometric Identities and Applications from "summary" of NCERT Class 10 Mathematics Solutions by JagranJosh
Trigonometric identities play a crucial role in simplifying trigonometric expressions and solving trigonometric equations. These identities are based on the ratios of sides of a right-angled triangle and are used to establish relationships between different trigonometric functions. By applying these identities, we can simplify complex expressions involving trigonometric functions into simpler forms, making them easier to work with. One of the most fundamental trigonometric identities is the Pythagorean identity, which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. This identity forms the basis for many other trigonometric identities and is essential for understanding the re...
